Quantum's LTO-4 HH tape drives protect your investment by providing backward read and write compatibility with LTO-3 media and backward read compatibility with LTO-2 media. With ultimate reliability and ease of use in mind, even at a 100% duty cycle, Quantum's rugged design builds on superior LTO technology and adds advanced features to create a new level of data protection. Quantum's LTO 4HH SCSI tape drives employ dynamic data rate matching to adjust to the speed of the host, reducing wear and tear on both drive and media and increasing performance, even on slower hosts. The drive also features a ultra-durable soft-load feature that automatically positions the data cartridge, and the highly reliable leader-capture mechanism virtually eliminates lost leaders, increasing the success of your backup and restore operations.
